Do not alter 000_testload.bk2and 000_newday.bk2. Without 000_newday.bk2, the game will not save after a boss fight at the end of the first in-game day and won't proceed. 000_testload.bk2 is used for transitions into battles.

user.ini stores the user specific configuration, in the user path. If the file is not present, you can copy typical contents from here. Or if you simply change any one of the available settings in-game the game will then create a user.ini at the mentioned location.
